Important metabolic conversion Aim of pathway Breakdown of glucose to pyruvic acid Conversion of glucose to glycogen Breakdown of glycogen to glucose Conversion Glycolysis . Glycogenesis Glycogenolysis Gluconeogenesis Formation of carbohydrates from non-carbohydrates . Glycolate cycle . Glyoxylate cycle sources (fats and proteins etc.) Also called C-2 cycle or photorespiration (in Plants only) Conversion of acetyl CoA to sugars (It is an example of gluconeogenesis), Conversion of pyruvic acid (acetyl CoA) to CO2 complete oxidative . Krebs' cycle break down.
Breakdown of fatty acids to form acetyl CoA. Reduction of CO2 to carbohydrates (in plants only) Reduction of CO2 to carbohydrates (in plants only) Fixation of atmospheric N2 to NH4 (In plants only) Fixation of atmospheric N2 to NO2 (In plants only) Conversion of ammonia to urea (in higher animals only) Anaerobic oxidation of pyruvic acid Addition of a phosphate group. Mostly this term is used . Beta oxidation . Calvin or C-3 cycle Hatch-Slack or C-4 cycle Nitrogen fixation Ornithine cycle Phosphorylation . Nitrification . Fermentation for ATP formation. Conversion of lactic acid back into pyruvic acid Metabolic pathway that removes amine groups from amino . Cori's Cycle . Oxidative deamination acids-leaving a keto acid and ammonia
